TofaZZ whom it may concern v Be it known that l.. ,lorry lvl. lil-Umm. a .citizen of the United .Stati esiding at Chicago, in the county of Cook and` State of illinois, have inventednew and useful-lm-V provenients in Regulators, of which the folA lowing is a full, clear, concise. and exact defscription, reference being had to4 the accompanying drawing, forming a :part` of this specification. i

Myinvention relates to improvements in regulators and is especially applicable to regulatorsused in connection with dampers. lt has for its object the production of a de vice that is adjustable for either pressure or vapor. i

A furtherobject isthe :production of a device `that-can be made universal `for` all heating boilers; f 1

fr further object.l is the production yolf a device in whichxthe fulcrum may `be shifted. A further object .is the productionr of 'a Jdevice ofcheap and simple construction and one -not liable to get out of order. 1

These and such other objects as may hereinafter appearare vattainedby my device, an embodiment df which is illustrated in :the accompanying drawings, in which` `Fig. 1 representsa sidev elevation of my device inoperative position; i

Fig. 2 represents an enlarged sectional view of my device; i Fig. 3 represents atop plan view of l3`ig.i2;y i n y Fig. l represents a sectional view through the line 4-4 of F ig. 2 looking in the direction4 indicated by the arrows; y

Fig. represents a horizontal sectional view on the line 5 5 of Fig. 2 looking in the direction indicated| by the arrows. x

Fig. 6 is a section on `the line V"6e-6 oi" Fig. 2. y ikeinumerals of reference indicate like parts in the several figures olf thedrawing.

Referring now to the drawings, A represents a boiler on which is mounted mydevice B adapted to operate the furnace door vC. Mounted on top of the boiler A. is a .steam pipe 6 in open communication with a diaphragm case 7 within which is mounted a series of diaphragme 8 on the top of which, is mounted a stem 9 sliding within the opening 10 in the top of the diaphragmfcase. No claims are made for novelty in the dia phragm in this application. On the top of the stem 9 is mounted the lever support 11 Specification of Letters Eatent.

carrying the lever 12 on which are preferably mounted weights 13, 14, and from one end 15 of the lever, aI chain 16 connected with the furnace door C. This lever support coniprises a lil-shaped yoke 17, having oppositely disposed threaded openings 18 in'its sides. Screws 19.19 extend through these openings and are provided with nuts 20 holding the screws in place.` :The ends of the screws are tapered. forming conical surfaces. Loosely fitting within the :yoke 17 is i a rectangular collary 22 through which the lever 12 passes, a screw .28 extending through the top. of the collar and engagingthe lever holding `it rigidly in 1 position. rl`he rectangular collar is pivotally mounted on the conical ends of ythe screws 19 as shown most clearly in Fig. lg the ends of the screws fitting within the concave sockets 24; in the sides of the rectangular collar. lt will beY noted that l provide three pairs of oppositely disposed sockets so that the hori-` Zontal position vof the lever may be varied if desired to accommodatek existing circumstances.

VAsshown in Figs. 2 and 5,1 provide a supf `,porting plate or guide 25 having a plurality.

of oppositely disposed ears 26 through which screw bolts pass7 securing the plate to the top of the casing. This plate is channelled out at its under.` surfaceproviding ifor the insertion of a squarepnut 27 and a longitudi-w` nal slot 28 in its upperfacepermit the inserticn of a screw bolt 29 engaging the nut 27. This slot is directly under the lever 12 and extends in a line therewith:

Mounted on the stem 9 is a connectoryoke 30 similar in all respects to the llever support 17. A rectangular `collar 81 through which the lever 12 passes is alsoinounted in this support, the collar and connector yoke being preferably precisely the saine as the A support shown in Fig. t. The only difference between the two` is that the connector 'yoke is adapted to move up and down as the pressure within the diaphragm `raises or lowers thefupper face thereof7 while the fulcruni'support is hel-d against vertical movement by the nut 27 within the channel or way olf the plate 25, b-ut can ybe slid forward` or back in Jthe line offdirection of the lever Vcal depressions 24EL in the collar 31.

scribed. The screws 19 are provided with conical points 21a for cooperation with cagiie collar 31 is provided with a screw 23a for securing itl to the leve-r 12 in any adjusted position. l Y

My device is adapted for use on various devices, the universal adjustment feature making it applicable for pressure or vapor, bychanging the fulcrum position and shift-- ing the weights and levers. It can also be used for the control of pressure reducing valves, pressure governors, etc., as well as for regulating the ordinary types ot boilers. Certain styles of boilers require an unusuallyv `large movement of the power lever in or er to open and close the damper. In other cases the connecting cha-ins become shortened or lengthened or bind on pulleys rendering it extremely essential tohave some adjustment features present, by means ot which the pressure may be accurately controlled. The eiiiciency ot' the regulator is also often greatly impaired by accumulation of rustVv and dirt where they are installed inplaces not easily accessible. By the use otmy shifting fulcrum, however, I canv secure as much orlittle power as desired and can render the device highly sensitive, such sensitiveness being easily adjusted by moving` thev fulcrum support toward or laway from the connector, and to do this it is simply necessary to loosen the nut 27 and the screw 23a, when the fulcrum support may be slid along to any position, for instance, that shown in dotted lines in F ig. 2. The nut 27 andthe screw 23a are then tightened, and the device is ready for'use. Vhen it is desired to remove the fulcrum support, the nut 27 is loosened, also the screw23"i and the tulcrum support 30 and the collar 31 can then be slipped off of the lever.

It is apparent that my device is capable of universal use on all heating boilers and is very easily installed.

While I have shown a specilic adjusting means through the medium of which the y' tulcrumsupport may be shifted on the diaphragm case, it is evident that the same re sults may be attained by a convex plate on a diaphragm case adjustably connected to the lever; this, however, or other devices of a like nature accomplishing the saine result comes well within the scope of my invention. Y

Having thus described my invention, what I claimV as new and desire to secure by Let ters Patent is:

l. A regulator comprising a diaphragm, a diaphragm casing, through said casing, a collar, a lever mounted on said stem and actuated thereby and supported by said collar, a fulcrum for said a diaphragm stem passingV permitting the vertical shifting of'saidrcol'- lars and lever. Y

In a device of the class described, the combination with diaphragm, a diaphragm casing, a stem extending through said casing,

a tulcrum support mounted on said casing,

a lever supported thereby, yoke members mounted on said stem and ulcrumsupport respectively, collars surrounding said lever and means integral with said collars for supf porting said lever in different positions of vertical adjustment.

4f. The combination with a diaphragm and diaphragm casing, of a fulcrum member mounted on said casing and laterally adjustable thereon, a lever pivotally connected with saidtulcrum member and vertically adjustable thereon, and a pivotalconnection be'- tweensaid lever and diaphragmV provided with means whereby the distance or' the lever from the diaphragm' may be varied.

5. 'The combination with a diaphragm and a diaphragm casing, of a yoke mounted.v on said casing and laterally'adjustable thereon;V a collar pivotal-ly mounted in said yoke and' vertically adjustable therein,a lever slidably secured in said collar and means for connecting said lever to said diaphragm.l

6. They combination with a diaphragm and diaphragm casing, of alaterally adjustable fulcrum, a lever fulcrumed thereon, a yoke mounted on said casing having a stem lpassing therethrough and connected with the diaphragm, a collar pivotally mountedvin lsaid yoke and vertically adjustable therein and slidably connected with said'lever.

7. The combination with a diaphragm and diaphragm casing, aV connection yoke, mounted on the casing and connected with the diaphragm, a fulcrum yoke'mounted on the eas-V ing and adjustable relatively to thev connection yoke, collars pivotally mounted in said yokes and vertically adjustable therein, and a lever slidably mounted in said collars.

In witness whereof, Iliave hereunto'sul scribed my name in the presence of a witness.
